A Novel Parallel Piezoelectric Six-Axis Force/Torque Sensor and its Simulation*
摘要
Abstract
According to the bottleneck contradictions of elastic style six-axis force sensor, a novel parallel piezoelectric six-axis force/torque sensor is proposed. First, the sensor's structure and operating principle are presented. Then its mathematic model is derived, and finite element model of sensor is established analyzed by ANSYS software. Finally, the sensor's input charge sensitivity, coupling interference, natural frequency,load transfer coefficient and decoupling matrix are obtained. Research results indicate that the sensor has advantages in simple and rational structure, correct mathematic model, nice manufacturability, good linearity, good rigidity, and natural frequency is more than 25 kHz, the interference error is less than 1％ with decoupling matrix. It can satisfy the requirements of sensor's design target.关键词
